Laser Kidney Stone Surgery vs Traditional Surgery: Key Differences

Kidney stones are a frequent source of pain, urinary problems and complications if they are left untreated. Small stones may be removed with medication and increased fluid intake, but larger or more complex stones will often require surgery.

Over the years, modern technology has provided different methods for removing or breaking up kidney stones, such as laser surgery, which is less invasive compared to traditional surgery methods. Understanding the differences between these two methods may help patients make informed choices about their healthcare options.

Understanding Kidney Stone Surgery

The aim in treating kidney stones is to remove them or break them down if they cannot be eliminated on their own. Your doctor will recommend a specific type of procedure for kidney stones based on numerous factors surrounding the stone, such as size, location and composition, as well as the number of stones and general health of the patient.

Historically, the majority of large kidney stones have been surgically treated using open surgery or by utilising more invasive techniques. With advances in technology, laser-based techniques for treating kidney stones have become more common. Lasers allow kidney stones to be removed or broken up with greater precision, with increased patient safety, and can shorten the healing process (faster recovery) compared to open surgery.

What Can I Expect During a Laser Surgery Procedure for a Kidney Stone?

Laser surgery for kidney stone removal is performed using an endoscope that is inserted into the urinary system and utilises lasers to break or fragment the stones. This technique produces high-precision stone fragmentation and is considered minimally invasive because it does not require an external incision.

The most commonly used technology for laser surgery is typically called the Holmium laser. This technology can be used to break up stones of various sizes and shapes from a variety of sources.

Comparison of Laser Kidney Stone Surgery and Traditional Surgery

1. Surgical Technique

Laser-assisted surgery for kidney stones uses a laser in place of traditional surgery, which requires a large surgical incision through the skin and surrounding tissues to reach the stone inside the body. The surgeon uses a scope to access the stone, then uses lasers to break it up and remove it.

Laser surgery is performed through the natural urinary tract without making an incision, while traditional surgery requires making a surgical incision into the skin and underlying tissues to reach the stone and remove it.

2. Invasiveness of Surgery

The primary advantage of laser surgery is that it is much less invasive than traditional surgery. No large incisions are made, so there is less damage to tissue and a lower risk of complications from damaging surrounding tissue. Traditional surgery involves a significant opening of the body to reach the kidney.

3. Pain Level

Because laser surgery does not create large incisions, patients usually have less pain after surgery compared to traditional surgery. Traditional surgery is usually much more painful than laser surgery since more tissue has been cut and needs to heal.

4. Recovery

Patients usually recover much faster after laser surgery than traditional surgery. Some patients return to their normal daily activities within just a few days to two weeks after a laser surgery, depending on the extent of the procedure.

On average, patients will not be able to start performing normal daily activities and/or resume their physical working duties for many weeks post-surgery after having traditional surgery.

5. Hospital Stay

Most patients who have laser surgery are discharged from the hospital the same day as the procedure, whereas patients undergoing traditional surgery are usually admitted and stay for several days.

6. Risks and Complications

The risks and complications associated with laser kidney stone surgery are generally minor and uncommon, whereas traditional surgery carries more risks and complications.

7. Long-Term Outcomes

Long-term outcomes are similar for both types of surgery, with the key difference being that patients who undergo laser surgery can participate in normal daily activities sooner than those who have had traditional surgery.

8. Blood Loss

Blood loss due to laser surgery is usually minimal, as the procedures are considered minimally invasive. The same cannot always be said for traditional surgery; it can involve greater blood loss, and some patients may require additional monitoring or intervention following a traditional surgical procedure, depending on their specific case.

Laser lithotripsy is highly effective for most kidney and ureteral stones, as it can treat stones regardless of composition. Traditional surgery continues to be an option for large or complex stones, or for stones with difficult access.

Who is a Good Candidate for Laser Kidney Stone Surgery?

• The stones are too large to pass naturally (via urination).
• The ureter is blocked because of the stones.
• You have recurrent (repeated) kidney stones.
• You have had other treatments, and your stones are resistant to them.
• You have persistent pain or urinary symptoms.

Your urologist will evaluate you, take detailed imaging tests, and ultimately make a treatment recommendation.

There are still situations that would require the use of traditional surgery over laser surgery, those are:

• Very large staghorn-shaped stones
• Very complex kidney anatomy
• Unsuccessful minimally invasive stone removal procedures
• More than one large stone that must be extracted directly
• Certain anatomical abnormalities

In these cases, performing the procedure directly on the kidney may offer the best chance of complete removal of the stone.

Conclusion

Surgery to remove kidney stones can be completed with a laser or using an open procedure. It is common for most patients to prefer laser lithotripsy to the traditional method because it is minimally invasive, very effective, has less pain after surgery, and allows the patient to recover faster than with the traditional method. There are still times when open surgery will be the best option for patients, such as with large or very complicated stones, or if it is necessary to remove the stone directly.

A urologist will evaluate the size, location, and difficulty of the kidney stone, as well as the patient's overall health, and will recommend the best treatment option for that patient. Choosing the best treatment method will improve results, reduce recovery time, and enable patients to resume their normal lifestyle sooner than if they did not choose it.
